SAN ANTONIO (Ticker) -- The San Antonio Spurs can claim their third championship in seven years Tuesday when they return home to play the Detroit Pistons in Game Six of the NBA Finals.

After claiming a thrilling 96-95 overtime victory in Game Five on Sunday, the Spurs have left themselves on the verge of becoming the seventh franchise to win three or more NBA titles.

Boston leads the way with 16, followed by the Minneapolis/Los Angeles Lakers (14), Chicago (six), Detroit (three), Philadelphia/Golden State Warriors (three) and the Syracuse Nationals/Philadelphia 76ers (three).

Robert Horry lived up to the nickname of "Big Shot Rob" by drilling a 3-pointer with 5.8 seconds to go in overtime of Game Five. The veteran forward, who already owns five championship rings, scored 18 of his 21 points in the fourth quarter and overtime.

Horry's heroics covered up for Tim Duncan's shortcomings down the stretch. Despite collecting 26 points and 19 rebounds, Duncan missed 6-of-7 free throws and a potential game-winning follow shot in the fourth quarter and missed two shots and committed a turnover in overtime.

If the Pistons want to repeat as the league champions, they will have to find a way to win here, where they have lost 10 straight contests. Detroit has not recorded a win in San Antonio since April 2, 1997 at the Alamodome.

To make matters worse, San Antonio has lost just five times at the SBC Center this season. Though two of the defeats came in the playoffs - one to Denver in the first round and one to Phoenix in the Western Conference finals - the Spurs won Games One and Two here by an average of 18 points.

Chauncey Billups, last year's Finals MVP, continued to be the Pistons' best scoring threat by scoring 34 points Sunday, but he missed two crucial shots in the final minutes while being harassed by defensive specialist Bruce Bowen.

A Detroit victory would set up the first Game Seven in the NBA Finals since 1994, when Houston edged New York.
